I just had a look and the channel I originally saw the video on has a Canadian flag on it.
So most likely a north American thing, but might show up in other places.
Oh, had a look online and it says it is somewhat common in Europe, like Northern Italy but originates from Eastern Europe and Russia.


I’ve seen some level 3000+ players as far back as months ago, but I think they glitched/exploited that level.
The highest legit levels I have seen are about 500 - 650 or so, 500 is when their icon turns gold.
It’s a real slog at times, but I will sometimes just do the weekly challenges and stop. Timed challenges really make the game feel like a chore.
The game feels really unbalanced as well, so many rounds it’s one team completely stomping the other and it’s not even close. Often 900 tickets to 0.
My friends and I had an evening like that as well, 3 times our team won by holding all the objectives and the game ended early. That’s no fun.
Side note, games like BF6 that cannot run in Linux are also what keep me from migrating to a Linux distro. I’d be off Windows in a second if all games ran on it no issues.
